Abstract:
:Corticotropin-releasing factor (CRF) stimulates rat retinal adenylate cyclase activity in a concentration-dependent manner. The half-maximal effect is obtained at 50 nM CRF and the maximal stimulation corresponds to approximately 90% increase of basal enzyme activity. The CRF effect is counteracted by the CRF antagonist alpha-helical CRF 9-41 with a Ki value of 40 nM. Other CRF-like peptides such as sauvagine and urotensin I are as effective as CRF with a rank order of potency of urotensin I greater than or equal to sauvagine greater than CRF. The sauvagine and urotensin I effects are not additive with that elicited by CRF. Moreover, the CRF stimulation is not additive with the increase of enzyme activity produced by vasoactive intestinal peptide or dopamine. The CRF effect is independent of the concentration of free Ca2+, is optimal at 5-10 mM MgCl2, and requires GTP. The results indicate that rat retinal adenylate cyclase is modulated by CRF via a receptor-mediated mechanism.
